The US box office this year stands at $10.1 billion, according to Boxoffice.com, just under last year’s all-time high of $10.8 billion.

A strong finish could make this a second straight record high year — but that could be in danger if the Christmas glut doesn’t cannibalize the total box office.

Two releases on Dec. 13 — “The Hobbit: The Desolation of Smaug” and “Tyler Perry’s A Madea Christmas” — could together gross $100 million on their opening weekend, taking some of the pressure off the Christmas openings.

The holiday rush is, in part, prompted by last-minute Oscar contenders from indie players and big studios, which must open before the end of the year to qualify.

“There is a prestige factor that goes along with a December release, and that often increases a film’s chance at scoring Oscar nominations,” Dave Karger, chief correspondent for the movie-ticketing service Fandango, told The Post.

Two movies, “The Hobbit” and “Anchorman 2,” have the biggest following on Facebook, said social media expert Jason Klein.

“Hobbit” has registered 3.7 million likes on the social network giant versus 3.2 million for “Anchorman,” said Klein.

“There’s a lot of concern on the specialty side,” one indie movie source said, “that they’re getting crowded out, with the exception of Justin Timberlake’s “Inside Llewyn Davis,” from CBS Films, which has done well in limited release.
